12/3/2023 0 Comments Define transistor and its typesBase: – It is present in the center of the both blocks (emitter and collector) and separates both.It collects a major amount of charge vessels provided by the emitter. Collector: – A larger size and simple dopped compared with emitter.It gives a large amount of majority charge carriers for current flowing. Emitter: – A semiconductor block with medium size but highly dopped.Now, let’s briefly discuss the three blocks of semiconductors in it. The arrow used in the symbol of an n-p-n or p-n-p transistor is the direction of the current flowing in it. The width of all three blocks of a transistor is different. Symbol of p-n-p transistor is shown in figure (b)(ii). p-n-p transistor: – In this, two blocks of p- type semiconductor are separated by a block of a n-type of semiconductor(figure (a)(ii)).Symbol of the n-p-n transistor is shown in figure (b)(i). n-p-n transistor: – It has two n- type semiconductor separated by a p- type semiconductor (fig a.(i)).Therefore, it is clear that there can be two types of junction transistors as shown in the figure below. All three are structured such as they form two p-n junctions between them. Internal structure of a bipolar junction transistor (BJT)īipolar junction transistor has three doped regions. Read further to know what is a bipolar junction transistor, its structure, why we call it bipolar and junction transistor, and what is its application in electronics. That means the current through the base terminal to the emitter terminal decides the current through the collector terminal to the emitter terminal. It has three terminal base, collector, and emitter. bipolar junction transistor (BJT) as an amplifierĪ bipolar junction transistor is a type of transistor that has three layers of semiconductor. Bipolar junction transistor (BJT) as a switch.Applications of transistor in electronics.Configurations of Transistor (Ways to connect a transistor in circuit).How a BJT works (what is going on inside it)?.
